Why browser is not throwing exception for syntax error?

Question

I accidentally wrote a wrong JavaScript syntax (I think so).

code is

  var temp = {};
    temp.a = 34;
    height:34, //should fail here.
    temp.b = 56;

jsfiddle

is syntax is correct?

Thanks.

Answer 1

A colon can be used to label a statement, and that's what's happening here. There are no errors in your code, it's intended behavior.

Edit: better resource on labels. :)
